It's ironic since there are also IP issues with Windows. I think maybe Syn'X should have started issuing warning letters to all those Windows end-users... They cannot be expected to have known the Unix code inside out and have spotted the IP right away surely?!?!
It's obvious that every OS will have routines in common 'cause they do the same job. You can't point at different sections of code and say "they've been obfuscated" when it's doing a generic OS task, and there's a lot of Unix-alike OS's out there... are they gonna sue everyone?
I hope this doesn't set some ugly legal precedent that affects, oooh, say... MorphOS?
